Top 10 list taken from a 3 month span of unit sales, from November 2006 through January 2007.

* North American Product ranking and market share are based on unit sales. All the data comes from National Purchase Diary (NPD) distribution channel software sales report. NPD captures 88% of all sales going through distribution channels.

It's not clear if "Ghost" in this context means all versions of Ghost, or only Ghost Solution Suite. Additionally, I suspect that "unit sales" means that if one company purchases 500 licenses of a product, then that counts as 500 (and not 1) in the tabulation.

P.S.: The same post also notes that Diskeeper has a "98.9% defragmenter market share". One wonders how Raxco can claim on its website that "PerfectDisk is the world's leading disk defragmenter" and that PerfectDisk "is preferred over Diskeeper by 9 out of 10 corporations"?
